Warning signs are all over Ohio roads, but new traffic stats show there hasn't been a big upswing in texting-and-driving tickets in the past year.The Columbus Dispatch checked the counties around Columbus, Cincinnati and Cleveland. The Ohio State Highway Patrol issued warnings in the first six months the law was in effect. And a patrol spokeswoman says it doesn't have a tally of citations written since that grace period ended six months ago, because the data set would be so small.The newspaper reports that 10 adults have been cited under the state ban in Franklin County, while Hamilton County has had 18. In Cleveland, two tickets for the statewide ban have been written, with more written under a local ordinance.
